pH响应型二硫化钼/葛根素纳米载药体系的制备与性能
Preparation and properties of pH responsive molybdenum disulfide/puerarin nanocarrier system
基于纳米二硫化钼(MoS2)表面缺陷位点对巯基的亲和性,构建了一种具有靶向性、抗耐药性及生物相容性良好的普朗尼克F68(PF68)与精氨酸-甘氨酸-天冬氨酸三肽(RGD)功能化修饰的二硫化钼/葛根素纳米载药体系PF68-PEI-MoS2-RGD(MPPR-PUE)。采用傅里叶变换红外光谱(FT-IR)、透射电子显微镜(TEM)和X射线光电子能谱仪(XPS)对合成材料进行表征;以葛根素为模型药物,通过紫外-可见分光光度计探究该载药体系的载药与释药性能,并通过细胞计数试剂盒-8(CCK8)和划痕实验考察纳米载药体系对肝癌细胞增殖和迁移的影响。结果表明,成功制备了MPPR-PUE纳米粒子,其载药量达46.91%±3.27%,包封率达到82.52%±0.82%。在pH为5.50的磷酸缓冲盐(PBS)溶液中,24 h药物的释放率可以达到61.60%±5.01%,具有pH响应性释药特性。MPPR-PUE纳米粒子对肝癌细胞增殖和迁移的抑制效果最好。
Based on the affinity of surface defect sites on nano molybdenum disulfide (MoS2) for thiol groups,a Pluronic F68 (PF68) and Arg-Gly-Asp tripeptide (RGD) functionalized MoS2/puerarin nano-drug delivery system,termed PF68-PEI-MoS2-RGD (MPPR-PUE),was designed and constructed.The synthesized materials were characterized using Fourier Transform Infrared Spectroscopy (FT-IR),Transmission Electron Microscopy (TEM),and X-ray Photoelectron Spectroscopy (XPS).Using puerarin as the model drug,the drug loading and release properties of this delivery system were investigated via ultraviolet-visible spectrophotometry.The effects of the nano-drug delivery system on the proliferation and migration of hepatocellular carcinoma (HCC) cells were evaluated using cell counting kit-8 (CCK-8) and wound healing (scratch) assays.The results demonstrate the successful preparation of MPPR-PUE nanoparticles,achieving a drug loading capacity of 46.91%±3.27% and an encapsulation efficiency of 82.52%±0.82%.In phosphate buffered saline(PBS)at pH 5.50,the cumulative drug release reached 61.60%±5.01% after 24 h,indicating pH-responsive drug release characteristics.The MPPR nanoparticles exhibited the most potent inhibitory effect on the proliferation and migration of hepatocellular carcinoma cells.
